SPECIFICATION forming part of Letters Patent No. 351,136, dated October19, 1886.

Application tiled July 1T, 1886. Serial No. 205,457. (No model.)

To all whom it may concer-7L.-

Be it known that I, WILLIAM J AcKsoN TAN- NER, a citizen of the UnitedStates, residing at Acworth, in the county of Cobb and State of Georgia,have invented a new and useful Improvement in Cultivators, of which thefollowing is a specification.

My invention relates to an improvement in cultivators, and it consistsin the peculiar construction and combination of devices that will bemore fully set forth hereinafter, and particularly pointed out in theclaims.

The object of my invention is to provide the cultivator with means foradjusting the shovels or plows laterally, so as to cause the saidshovels or plows to work at any desired distance apart, or with onealmost immediately in rear of the other, thus adapting the device to beemployed either as a single or as a double shovel cultivator.

In the drawings, Figure 1 is a side elevation of a cultivator embodyingmy improvements. Fig. 2 is a top plan View of the same. Fig. 3 is adetail vertical longitudinal sectional view, taken on the line x x ofFig. 2. Fig. 4 is a detail perspective view of one of the plow-feet andthe connections.

A represents the beam, and B represents the handles, which are attachedto the rear end ofthe beam in the usual manner.

C represents a pair of parallel bars or arms, which are attached to theunder side of the beam by means of bolts D, which extend verticallythrough the said beam and through the centers of the said bars or arms.

E represents a longitudinal plate, which is secured on the ends of thebolts D and bears against the under sides of the bars O. The front endof the said plate extends forwardly a considerable distance from thefront bolt, D, and through the beam, and through the front end of theplate E passes a vertical bolt, F. Nuts G are screwed onto the lowerends ofthe bolts D, so as to clamp the plate E against the lower side ofthe centers of the bars C, and a clamp-nut, H, is screwed onto the lowerend of the bolt F, and bears against the under side of the front end ofthe plate E. In the outer ends of the bars C are made vertical openingsC.

I represents a pair of plow-feet, each of which is wrought or cast froma single piece of metal,

and is provided with a curved standard, K, and a horizontal bar orplate, L. In each of the said bars or plates, at the extremitiesthereof, are made vertical openings M. The standards K are provided withvertical slots N, and in the upper ends of the said slots are bolted thelower ends of braces O. A bolt, l), passes through an opening made inthe rear end of each brace O, and through the opening in the rear endot' each of the plates L, and also through the opening O in the outerend of the rearward parallel bar O, thus pivoting the said plates L tothe said bars, and also securing the rear upper end ofthe braces O rmlyto the rear end of the said plates. A bolt, R, passes through theopening in the front end of each plate L, and also through the openingin the outer ends ofthe front bar O, thus pivoting the front ends of theplates L to the outer ends of the front bar O.

The plows or shovels S are attached to the front sides of the slottedstandards by means of bolts which pass through the slots in thestandards in the usual manner, as shown.

From the foregoing it will be understood that the bars O are free toturn on the under side of the plow-beam, so as to move the plows orshovels laterally and thus adapt them to work at any desired distanceapart, thus adapting the cultivator to be used in cultivating rows ofplants at any distance apart, and also adapting the cultivator to beused either as a single or as a double shovel cultivator. The arms O aresecured at any desired adjustment by tightening the nuts G and H, andthus causing the plate E to bear firmly against the said arms, and thusclamp them rigidly to the under side of the plow-beam. In order tochange the adjustment of the plows or shovels it is only necessary torst loosen the nuts G and H, when the bars C may be readily swung to anydesired position.

By providing the plow-feet with the braces O great strength anddurability is obtained.

Having thus described my invention, I claim- 1. The cultivator framecomprising the beam, the parallel bars C, the clamping-plate E, thebolts extending through the plow-beam, the bars C, and the plate E, incombination with the plow-feet comprising the curved Standards K,havingthe horizontal rearwardly- IOO extending arms 0r plates L, and thebraces O, shovel, and its upper end connected to the rea-r Io and thepivotal bolts connecting the plates o1l end of the arm or plate L by aloolt` as set forth. arms to the ends of the bars O. In testimony that Ielai n1 the foregoing as 2. The plow feet comprising thev curved my ownI have hereto afxed my signature in standard K, having the horizontalrearwardlypresence of two witnesses.
